MACHINE'FOR FORMING CALKS ON HORSESHOES.

Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed October 12,, 1912. Serial No. 725,385.

I To all whom it may concern Be it known that I, JOHN D. HALL, a citizen of the United States, residing at Orr: ville, in the county of Wayne and State of Ohio, have invented a new and useful Machine for Forming Galks on Horseshoes, of which the following is a specification.

My invention relates to improvements in machines for forming the heel calks upon horseshoes and has for its object, to provide a mechanism by which the heel calks may be formed and finished without reheating the shoe. This object together with other objects readily apparent to those skilled in the art may be attained by the construction illustrated in the accompanying drawings, although the invention may be embodied in other forms, the construction illustrated beingchosen by way of example.

Figure 1 is a front elevation of the ma chine. Fig. 2 is a rear elevation. Fig. 3 is a plan view with the top plate removed and parts broken away. Fig. 4 is a vertical longitudinalsection upon the line 44, Fig.

3. Fig. 5 is a vertical transverse section on the line 55, of Fig. 4. Fig. 6 is an end elevation. Fig. 7 is a perspective view of a portion of a horseshoe showing one of the heel calks completed. Fig. 8 is a longitudinal sectional view of a modified form of 5 my device. Fig. 9 is a top plan View with the upper plate removed and parts brokenaway, of the modified form. Fig. 10 is a; perspective view of a portion of a horseshoe g 1 is attached one end of the pitman rod 43,

showing one of the shoe calks completed.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

1 indicates plates 2 and 3' respectively. The die block At one end of themachin'eifs located a shaft 13 journaled in suitable bearings 14 upon the posts 4 and provided at one end with a pulley 15. The cams16 and 17 are fixedly mounted upon the shaft 13 and are adapted to bear against'the ends of the die block 6 a suitable support for the machine proper. The upper and lower plates 2 '2 and 3 respectively are spaced apart by? means of the corner posts 4, which are connected to said plates by any suitable means such as the bolts 5. The die block 6 and the horseshoe holding block 7 are slidably mounted within the grooves 8 and 9 in the Upon the rear end of the shaft 13 is lo.-

arm 25 of the die 26, said die being provided with a plunger 27 adapted to reciprocate within the cylindrical opening '28 lo cated in the die block 6.

Journaled in suitable bearings 29 upon the upper plate 2 is a rock shaft 30 provided upon its rear end with a rock arm 31 to the end of-which is attached one end of the pitman rod 32, the opposite end of said pitman rod being. attached to the wrist pin 19 upon the pitman wheel 18. Intermediate said bearings 29 is located a cam33 upon the shaft 30, said cam being adapted to bear upon the upper face of a plunger 34, said plunger being provided with an arm 35 journaledat 36 to a block 37 located upon the plate A spring 38 located in a socket 39 in the plate 2 adapted to bear against the lower face of the arm 35 and normally hold the plunger 34 in contact with the cam 33. A similar rook shaft40 is journaled in i 1 suitable bearings 41 upon the lower plate 3, said rock shaft being provided upon its rear end with a rock arm 42, to the end of which the opposite end of said pitman rod being arm 45 journa'led'at 46 to a block 47 located upon' the plate 3. A spring 48 located in a socket 49 in the plate 3 is adapted to bear against the lower face of the arm 45 and normally hold the plunger 44 in contact 1 with the -cam 43. i

A gage block 50is slidably mounted in the transverse grooves 51 and 52 in the upper and lower plat'es2 and '3, respecsaid block. A vertical bar 54 is located in front of the block 50 and is supported by the plates 2 and 3 in any suitable manner such as the screws 55. Set screws 56 are ,tively. 'Guide pins 53 are provided upon carried. by said bar and adapted to bear right,

against the forward face of the block 50 for adjusting the same.

A suitable weight 57 is suspended by means of a cord 58, the ends of which pass over the shaft 13 and are secured to the die block 6 and holding block 7 as at 59 and 60 respectively.

The operation of the device is as follows: The heels of the horseshoe as shown in dotted lines at 61 in Figs. 1, 3 and 4, are placed between the guide pins 53 so as to bring them upon either side of the reduced portion 62 of the die 26, their ends striking the face 63 of the die 10. Then as the shaft 13 is rotated the cam 16 will move the die block 6 to the the shoulder 12 upon said die block striking the heel of the horseshoe and bending it at right angles upon the inner face 64 of the gageblock 50. At the same time the shaft 22 will be rocked by means of the pitman 2O drawing the die 26 toward the die block 6, the shoulder 65 upon the die 26 coming in contact with the turned-over end 66 of the horseshoe heel. The shoulder 11 will then be brought into contact with the face 67 of the horseshoe heel and atthe same time the cam 17 will move the holding block 7 forward until it comes in contact with the horseshoe, thereby holding it firmly in place during the rest of the operation. During this operation the cams 33 and 43 will be brought to bear upon the plungers 34 and 44 respectively, thereby squaring up the side faces-68 and 69 of the horseshoe heels between said plungers and the faces 70 upon the die 26. A still further rotation permits said plungers 34 and 44 to be withdrawn and the weight 57 pulls the die blocks 6 and holding blocks 7 back to the normal position when the horseshoe may be removed and another one inserted for the next operation. It will be noticed that only one revolution is necessary to com plete the operation.

By adjusting the gage block 50 it will be seen that the heel calk will be made thicker or thinner as desired.

For the purpose of forming a sharp calk upon the heels for use upon icy pavements I have provided a modification of my de vice whereby such calks may be formed. In the modified form the reduced portion 10 upon the die block 6 is provided with a pair of rollers 71 journaled at their lower extremities in suitable apertures in the reduced portion 10, their upper ends being journaled in slot-s such as 72, and held in place by any suitable means as the caps 73. Referring to Figs. 8 and 9 of the drawings it will be seen that the rollers 71 are flush with the face of the reduced portion 10 of the die block. A die 26 is used in this form of invention, said die having upper and lower faces 70 The gage block 50 used in this form of the device is provided with extensions such as 74, which project between the faces 70 of the die 26 and the plungers 34 and 44. These extensions are provided with beveled faces such as shown at 7 5.

The operation of the modified form of the device is practically the same as in the first form. Each roller 71 will pass across the face 76 of the calk, forcing said calk between said roller and the beveled face of the gage block 50, .thereby, forming the beveled face 77 upon the calk. The plungers 34 and 44 will operate in the same manner as in the other form of the device, compressing said calk between said plungers and the face 70 of the die.
